[0006] (2)提取：以二甲醚为溶剂对颗粒料进行提取，颗粒料与溶剂的重量比为1 ： 0.8〜6，提取温度为10〜45°C，提取时间为10〜60min;提取结束后进行固液分离， 对分离的固相按上述提取工艺条件重复提取2〜8次，经提取后的固相即为辣椒粕； [0006] (2) Extraction: dimethyl ether as the extraction solvent to particulate material, the particulate material to solvent weight ratio of 1: 0.8~6, extraction temperature is 10~45 ° C, the extraction time is 10~60min; after the end of the extraction liquid separation, the separated solid phase extraction conditions according to the above extraction was repeated 2~8 times, that is, the solid phase after the extraction meal pepper;

[0007] (3)回收溶剂：对（2)分离的液相进行过滤或沉降，去除其中的细小杂质，减压分离为气相和浓缩物，将气相压缩液化回收溶剂； [0007] (3) recovery of the solvent: (2) will be separated from the liquid by filtration or sedimentation, wherein the fine impurities removed under reduced pressure and the concentrate separated into a gas phase, the solvent is recovered liquefied compressed gas;

[0008] (4)分离产品：将（3)分离的浓缩物控制温度在20〜50°C，表压小于_0. 085Mpa 的条件下，脱除水分及挥发物，得到辣椒红色素油膏。 [0008] (4) separating the product of: (3) separate temperature control in the concentrate 20~50 ° C, under a gauge pressure of less than 085Mpa _0, the removal of moisture and volatile matter, to obtain red pigment ointment.

[0009] 使用本发明的方法提取辣椒红色素油膏，不受原料品种限制，能充分利用原料资源，提取率高，渣残低，辣椒粕的色泽浅，不仅适合低辣味度的辣椒，更适合高辣味度的辣椒，生产成本低，市场竞争优势明显。 [0009] The extraction method of the present invention is an ointment capsanthin, varieties of raw materials is not limited, and can make full use of raw material resources, extraction rate, low residual slag, light color meal pepper, chili not only for a low degree of hotness, and more suitable for a high degree of spicy chili, low cost of production, distinct competitive advantage.
